A 2-stage rotary compressor is provided to prevent coupling deformation between a lower bearing and a lower cover and keep a sealed state between the lower bearing and the lower cover. A first bolt(B1) couples a lower bearing(161), a low pressure cylinder(121), a central plate(140), a high pressure cylinder(131) and an upper bearing(162) from the bottom in sequence. A lower cover(171) and the lower bearing, which form an intermediate pressure chamber, are coupled by a second bolt(B2) together with a gasket(G) for preventing the deformation of the lower cover and the lower bearing while keeping a sealed state therebetween. |
